You still have to have the coupon in hand. You will need to print it from the web site and have it with you when checking in, or when dining; depending on the offer you are using. Complete instructions are on the web site.

FWIW, web offers were introduced in tandem with coupon books a couple years ago. It was suppose to go to all web coupons only last year, although some of us still received paper coupon books. It was announced and discussed here on FT ad nauseum and generally thought to be a good thing since Marriott always had a problem getting the paper coupons out the door and in our hands in a timely manner. I prefer the paper coupon books too, but routinely only use them maybe once a year if I a m lucky since Europe and Resorts are excluded for the most part.
